What is water conservation
the practice of using and managing freshwater resources efficiently to prevent waste and ensure availability for current and future needs, including human, environmental, and agricultural uses
What is rainwater harvesting?
the collection and storage of rain for later use, preventing it from becoming runoff
name three examples of saving water
short shower, turn off tap, and install water saving devices.
What is a dam and a reservoir?
A dam is a physical barrier, often made of concrete, earth, or rock, that is built across a river or stream to stop the flow of water and create a body of stored water. A reservoir is the artificial body of water that forms behind the dam due to this blockage.
What are Desalination plants?
facilities that remove salts and other minerals from seawater or brackish water, producing fresh, potable water for human use, such as drinking, irrigation, or industrial applications.
explain the disadvatges of irrigation?
waterlogging and soil salinization, which reduce soil fertility and can damage crops; high initial and operational costs; depletion of water resources; spread of diseases due to stagnant water; and environmental damage from water pollution and habitat alteration
What is an aquifer?
An underground layer of permeable rock, sand, or gravel that holds and stores groundwater, which seeps in from precipitation above.
explain enhancing natural wetlands
actively improving the health and functionality of existing wetlands to maximize their ecological benefits, such as water filtration, flood control, and habitat for wildlife
Name the different ways to prevent evaporation for crops
compost, mulch, black plastic.
What is a fossil aquifer?
This trapped "fossil water," often from melting glaciers of the last ice age, remains sealed by impermeable rock layers and is considered a finite, non-renewable resource
name a advantage and disadvantge of dams
Advatnge: their ability to provide controlled water supply for hydroelectric power, irrigation, and drinking water.
Disadvantage: Sedimentation
What is aqauponics?
a system of aquaculture in which the waste produced by farmed fish or other aquatic creatures supplies the nutrients for plants grown hydroponically, which in turn purify the water.
